A Short Review of Multimodal Biometric Recognition Systems

Multimodal biometric systems, which combine two unimodal recognition systems into one single method, can be used to overcome the limitations of individual biometrics. This paper will do a short but critical review on recently developed for enhancing multimodal biometric systems. As can be seen from Celik et al. [1] the biometric information can be combined using different types of fusion of biometric data at different levels, i.e., at the feature level, matchingscore level or decision level. The biometric data classification and throughput of the biometric recognition systems can be carried out by analysing these fusion levels.
